STAT, or the self-approximating transluminal access technique, has been previously described and involves the dissection of a submucosal tunnel for peritoneal or mediastinal access from the esophagus and stomach. The objective of this study was to assess the safety and reliability of gastric access and closure in a porcine experience using STAT for natural orifice transluminal endoscopic surgery (NOTES).
A review of the experience using STAT access tunnels for intraperitoneal access was performed in 39 female pigs at a university animal lab. All animals underwent a predetermined NOTES surgical procedure using a STAT transgastric access tunnel based on a specific protocol. Details of the procedure, complications, and clinical course were documented. Necropsy was performed at 2 weeks. The main outcome measurements were clinical or necropsy evidence of gastrostomy site leak or inadequate access site closure.
STAT was successful in providing safe peritoneal access in all animals. The width of the tunnel ranged from 1.5 to 5.5 cm and the length was up to 27 cm. There was no evidence of gastrostomy site leak in any animals. One animal required a single laparoscopic suture to help with tunnel closure.
STAT provides safe transgastric access and allows secure closure of the gastrotomy site.
STAT，即自逼近经腔入路技术，此前已有描述，涉及从食管和胃中解剖出用于腹膜或纵隔入路的黏膜下隧道。本研究的目的是评估使用 STAT 进行经自然腔道内镜手术（NOTES）时，猪模型中胃入路和闭合的安全性和可靠性。
在大学动物实验室，对 39 头雌性猪进行了使用 STAT 入路隧道进行腹膜内入路的经验回顾。所有动物均按照特定方案，使用 STAT 经胃入路隧道进行了预定的 NOTES 手术。记录了手术过程、并发症和临床经过的详细情况。在 2 周时进行尸检。主要观察指标为胃造口部位漏出或入路部位闭合不足的临床或尸检证据。
STAT 成功地为所有动物提供了安全的腹膜内入路。隧道的宽度为 1.5 至 5.5 厘米，长度可达 27 厘米。没有动物出现胃造口部位漏出的证据。有 1 只动物需要单针腹腔镜缝线帮助闭合隧道。
STAT 提供了安全的经胃入路，并允许安全闭合胃造口部位。
